Aside from the open-sourced nature of the project, the possible widespread applications of the technology also makes it noteworthy. It could be a plausible alternative to mechanical traps, as well as chemicals that often damage the environment and target non-pest insect species. Not to mention, it’s cheaper (the paper notes that all devices cost not more than $250) and more compact than other current pest-controlling technologies.

That being said, although the prototype is suitable for academic research, there’s a lot more to be done before it can be deployed on a larger scale. For example, the paper notes that a smaller laser point would be more effective at killing the roaches but is difficult to implement experimentally. The ability to precisely control which parts of the cockroach’s bodies were hit would also be helpful, the paper says.

Pure water is an almost perfect insulator.

Yes, water found in nature conducts electricity – but that’s because of the impurities therein, which dissolve into free ions that allow an electric current to flow. Pure water only becomes “metallic” – electronically conductive – at extremely high pressures, beyond our current abilities to produce in a lab.

But, as researchers demonstrated for the first time back in 2021, it’s not only high pressures that can induce this metallicity in pure water.

For proper operation, drones usually use accelerometers to determine the direction of gravity. In a new study published in Nature on October 19, 2022, a team of scientists from Delft University of Technology, the CNRS and Aix-Marseille University has shown that drones can estimate the direction of gravity by combining visual detection of movement with a model of how they move. These results may explain how flying insects determine the direction of gravity and are a major step toward the creation of tiny autonomous drones.

While drones typically use accelerometers to estimate the direction of , the way flying achieve this has been shrouded in mystery until now, as they have no specific sense of acceleration. In this study, a European team of scientists led by the Delft University of Technology in the Netherlands and involving a CNRS researcher has shown that drones can assess gravity using visual motion detection and motion modeling together.

To develop this new principle, scientists have investigated optical flow, that is, how an individual perceives movement relative to their environment. It is the visual movement that sweeps across our retina when we move. For example, when we are on a train, trees next to the tracks pass by faster than distant mountains. The optical flow alone is not enough for an insect to be able to know the direction of gravity.

• https://youtu.be/sEt0nIBPL24 Deeper dive into Helion’s materials, methods, and fusion approach. (unlisted bonus content)

• Organizations all across the world are racing to achieve a fusion power breakthrough. Many critics say nuclear fusion is impossible, but Helion Energy believes they’ve cracked the code…

If you could design the perfect energy source, it would have an inexhaustible supply of fuel, be environmentally friendly, not take up much space, and have a high degree of safety.

The fuels considered for fusion power have traditionally all been isotopes of hydrogen, but there are better fusion reactions using elements like helium-3. Nuclear Fusion 3.

What is nuclear fusion? Nuclear fusion explained: an experimental form of power generation that harnesses the energy released when two atoms combine.

How does nuclear fusion work? Every atom is composed of a nucleus and one or more electrons. The nucleus is made up of protons, and neutrons. A fusion reactor heats fusion fuels into plasma and fuses light elements into heavier elements.

Strange libraries of supplementary genes nicknamed “Borg” DNA appear to supercharge the microbes that possess them, giving them an uncanny ability to metabolize materials in their environment faster than their competitors.

By learning more about the way organisms use these unusual extrachromosomal packets of information, researchers are hoping to find new ways of engineering life to take a big bite out of methane emissions.

In the wake of a study publicized last year (and now published in Nature), researchers have continued to analyze the diversity of sequences methane-munching microbes store in these unusual genetic depositaries in an effort to learn more about the evolution of life.

A drug has been identified by researchers at Tokyo Medical and Dental University (TMDU) that replicates the benefits of exercise on mice’s bones and muscles.

You can look and feel better by keeping up a regular exercise schedule, but did you know that exercise also supports bone and muscle health? Locomotor fragility, which affects people who are unable to exercise, causes the muscles and bones to deteriorate. Recently, Japanese researchers discovered a new drug that, by producing effects comparable to those of exercise, may help treat locomotor frailty.

Physical inactivity can result in a weakening of the muscles (known as sarcopenia) and bones (known as osteoporosis). Exercise dispels this frailty by boosting muscular strength and suppressing bone resorption while simultaneously promoting bone formation. Exercise therapy, however, cannot be used in every clinical situation. When patients have dementia, cerebrovascular disease, or are already bedridden, drug therapy may be very helpful for treating sarcopenia and osteoporosis. However, there is no one drug that targets both tissues at the same time.

A new discovery could be a game-changer for patients with type 2 diabetes. Researchers at the Diabetes, Obesity, and Metabolism Institute (DOMI) at the Icahn School of Medicine at Mount Sinai have discovered a therapeutic target for the preservation and regeneration of beta cells (β cells), the cells in the pancreas that produce and distribute insulin. The finding could also help millions of individuals throughout the globe by preventing insulin resistance. The study was recently published in the journal Nature Communications.

Nature Communications is a peer-reviewed, open access, multidisciplinary, scientific journal published by Nature Research. It covers the natural sciences, including physics, biology, chemistry, medicine, and earth sciences. It began publishing in 2010 and has editorial offices in London, Berlin, New York City, and Shanghai.
